Can't login to facebook, myspace or my e-m...

my daughter and her boyfiend have been using their myspace with no problem then on saturday they tried to login into account and it just kept going back to the login page. Then it finally said to many invalid login attempts and for them to put in a text code even after they did that it still did nothing. My daughter had a couple of her fiends try on their computers but it said the same thing on their computers. She is also having problems getting into her live.com e-mail and her facebook account. I have been haveing problems getting into my yahoo e-mail account. I finally decided to just start a new e-mail account with live.com. But I have no problems getting into my myspace account. Are all three problems related? She also deleted her temporary internet files and old cookies. Can it be fixed and what should she do? thank-you
